    I’m not usually the one to write reviews. Actually, this is my first review ever. I just wanted to say this certificate has saved my company tons of money. If we hadn’t encrypted our emails in time, the consequences could have been devastating.

    We traced a serious security incident back to email hacking. After we installed the CPAC Enterprise on our systems, no more data breaches occurred.

    The validation seemed a bit exhaustive, to be honest. The certificate was issued in 6 days. Security wise, it’s a powerful product, and we’re very happy with its performance.

    This certificate secures our internal emails and documents, and, on top of that, enables the two-factor user authentication. I can’t believe it is so affordable.

Here is a list of the most common questions our customers have when buying a Sectigo CPAC SSL Certificate:

What are Multi-Year SSL Subscription Plans?

Starting with August 19th, 2020, the maximum duration of publicly-trusted SSL/TLS certificates issued by all Certificate Authorities (CAs) has been set to a maximum of 13 months.

However, in order to make your SSL Management process time-saving and cost-effective, the CAs and SSL Dragon are offering you the 2 Year and 3 Year SSL Subscription Plans.

This means that you can still buy a 2 or 3 year SSL Certificate and continue to benefit from multi-year discounting, while still remaining compliant with the CAB Forum SSL requirements.

How the Multi-Year SSL works?

Due to security reasons, your SSL certificate is initially issued with a maximum 1-year validity.

Prior to the expiration of your certificate, SSL Dragon, on behalf of the CA, we will issue a free replacement certificate for an additional 1-year certificate, according to your Subscription Plan.

You will need to validate & install the replacement SSL:

a. If you have a Domain Validation SSL Certificate, a short verification of your domain name will be required via Email, HTTP, or DNS in order to issue the 1-yr replacement SSL.

b. If you have a Business or Extended SSL Certificate – an additional Business Validation/Extended Validation recheck and callback process will also be required.

You can still reissue your certificate at any time and as many times as you like during your Multi-Year SSL Subscription Plan.

Sectigo Personal Authentication Certificates provide you the highest level of protection by enabling end-to-end encryption of your email communications. By signing and encrypting your outgoing email messages, you protect them from Man-in-the-Middle attacks, https proxies, or packet-sniffers, therefore your messages can’t be intercepted and decrypted by a malicious third party.

Encrypting Email Messages guarantees their privacy and integrity, while digitally signing the messages authenticates you as being the genuine sender. In this way, you will secure yourself and your business from accidental or fraudulent data exposures, privacy breaches, and other potential security threats associated with business communication. 


Sectigo Personal Authentication Certificate lets you easily sign any valuable and critical personal or company document, therefore ensuring compliance with industry requirements of digitally signed documents. By digitally signing the document, you identify yourself as the authentic document signer and certify its integrity by proving that your document hasn’t been altered since it was signed. In this way, CPAC SSL Certificates help you migrate from ink & paper to digital workflows of contracts, sign-offs, request forms and other important company documents, working in tandem with or replacing the visible signature feature in Microsoft® products such as Microsoft Office Suite, Open Office Suite, VBA Macros and more.



 Sectigo Personal Authentication Certificate helps businesses reduce the risks and threats associated with using standard passwords by enabling the two-factor authentication of users. If you need a stronger guarantee that the person logging into your company network or account is your legitimate employee, CPAC SSL Certificates will allow you to secure your sensitive and private customer or corporate data by enabling the industry standard used by banks all over the world – two-factor authentication – seamlessly integrating the certificate as a second authentication element. In this way, you will protect your company access, including remote, from any hackers attempting to steal usernames and passwords. 

Sectigo Personal Authentication Certificates were designed for individuals and businesses who are looking at implementing the best web security practices, such as email & document encryption and user two-factor authentication. However, each CPAC SSL Certificate was designed to fit a particular need. Just like DV, BV, and EV SSL Certificates, CPAC SSL Certificates come with different validation requirements which enable certain certificate fields:

  • CPAC Basic – requires Domain Control and displays only your email in the SSL Certificate
  • CPAC Pro – requires Domain Control and Identity Verification in order to display your email, First and Last Name in the SSL Certificate
  • CPAC Enterprise – requires Domain Control, Identity Verification, and Organization Validation in order to display your email, First and Last Name, as well as Company Name and Address in the SSL Certificate.

Based on your actual needs, you can now decide which Sectigo Personal Authentication Certificate is the best option for you, providing you an enhanced web security of your business activity. 

To add your Company Name and TAX/VAT number, you have to login into your SSL Dragon Account and follow these steps:

  1. Click on the “Hello, *Your Name*” button on the right top side of your account dashboard and select “Edit Account Settings”;
  2. On the ‘My Details’ page, you will find the ‘Company Name’ and ‘Company TAX/VAT ID’ field;
  3. Fill in these fields with the necessary information then click on ’Save Changes’. 

After you perform the above steps, your SSL Dragon account and all your invoices will be automatically updated with this information.


There are many different ways to install an SSL Certificate, and they all depend on your SSL Certificate brand, the webserver type, the operating system on your server, and the web hosting panel that you have on your server.

These being said, please check our Installation Articles to get detailed instructions on how to install your SSL Certificate on about 44 different server types, hosting panels, and operating systems.

Also, here are links to documentation on how to install your SSL Certificate on your server, based on the SSL Certificate brand that you have:

We always recommend you get specialized help with your SSL Certificate installation. If you have a web developer or a system engineer, then they would be the right people to help you with your SSL Certificate installation.
